  • I’ve worked on both, and as long as I can plug the laptop in a nice monitor, with keyboard and mouse I don’t care that much. Laptops great for mobility, and the keyboard and trackpad, well you get used to it, and doesn’t bother you that much. For myself, its wfh and then going to the office, isn’t a big deal, all stuff is on the laptop and things are synced if I need to do disaster recovery. It depends on the situation, would you benefit from it. if not, desktop’s fine


  • I’d say, what kind of security are you talking about? Apart from standard HTTPS to keep things encrypted, there are other layers if you want to keep your service exposed to the internet.

    Also how things are installed and if they are correct, proper file permissions. nothing different than having it on the server somewhere. You just need to keep thing up to date and you’ll be fine.










  • I’m running both, via docker.

    Here’s the basic setup:

    NGiNX is standard installation, using certbot to manage the SSL certificates for the domains. Setup is via Nginx virtual hosts (servers), separate for Lemmy and Mastodon. Lemmy and Mastodon run each in their Docker containers, with different listning ports on localhost.

  • No problem. I’ll just go with a oversimplification.

    The idea is that you just take whatever traffic hits port 443 and use iptables rules to route the traffic elsewhere, or in this case

    Client --> [port 443] --> [iptables] --> [ port 443 home server]

    So, it’s basically just traffic forwarding from the VPS directly to your home server, being directly to your ISP IP address, or via wireguard IP address.

    So all the traffic you are sending back from the VPS is in its original state, and the actual processing happens on your local/home server.

    On the home server you have a Web Server of your choice listening on port 443 with, loaded with your SSL certificates. So, request is made to the VPS IP address, iptables just forward the packets to your home server, and there is where the SSL/TLS termination happens. The client negotiates the TLS connection directly with your home server, and web server on your home server then sends the request where you tell it to ( reverse proxy to a docker container, or it serves the content directly).

    With this, you basically turn the VPS into a passtrough for traffic.

    Here’s a quick test I did… the two servers are connected with Wireguard mesh.

    On the VPS you need have net.ipv4.ip_forward=1 .

    net.ipv4.ip_forward=1
    

    Your iptables rules should be. Obviously on the home server you can run the webserver on any port you like, doesn’t have to be 443. But let’s keep it 443 for the sake of argument.

    iptables -t nat -A PREROUTING -p tcp --dport 443 -j DNAT --to-destination HOME_SERVER_IP:443
    iptables -t nat -A POSTROUTING -j MASQUERADE
    

    If you want to drop the rules:

    iptables -t nat -F
    

  • Best option is to directly NAT traffic from VPS to your home server, either directly to your IP or set up a wireguard peer and send traffic via wireguard to your local and do the SSL/TLS termination on your local.

    You are best exposing just 443 port on the VPS and moving that traffic over wireguard. Server will have your local public key on the server, and you could implement a wireguard key rotation to change them frequently.

    Traffic sent back will be encrypted with the certificate, and even if they get the wireguard server key, you can rotate it, but still they will see encrypted packets.

    It depends what kind of things you’re doing on your local. If it is just a website thing, then reverse proxy is fine. Anything other than that, NAT would be cleanest one.

    LUKS on the disks would encrypt it the data on the block storage level, and, in theory, they should not have a way of reding block storage files directly. But since it is a VPS they can, technically, gather data from host memory.

    Next step might be going down a dedi server route, Luks encryption on disks. Only thing thats needed there would be sufficient network pipe.
